Objectives: The purpose of this study was to describe the pattern of metaxalone ingestions by young children reported to poison control centers.

Methods: Cases were all metaxalone ingestions by patients aged 0 to 5 years reported to Texas poison control centers during 2000 to 2007. Cases with multiple substance ingestions and lack of follow-up were excluded. Cases were analyzed for selected demographic and clinical factors.

Results: Of 148 total cases, 56.8% were boys. The distributions by management site were 56.1% on-site, 22.3% already at/en route to a health care facility, and 21.6% referred to a health care facility. Final medical outcomes were no effect for 90.5% cases, minor effect for 8.1%, moderate effect for 0.7%, and major effect for 0.7%. Specific clinical effects reported were drowsiness (11), vomiting (3), agitation (2), rash (1%), tachycardia (1), and ataxia (1).

Conclusions: Pediatric metaxalone ingestions reported to Texas poison control centers usually resulted in minor or no effect. Most ingestions did not require hospitalization.
